The text in Section 7.8 says that if you enter idle, then you leave in one of two ways: pace, or reduce your cwnd to init_cwnd.  We're choosing to not really spend energy on performance for the non-pacing cases, because pacing is an undocumented BCP.

When not pacing, it's reasonable to do something along the lines of what @mikkelfj suggests -- indeed that's roughly what NewCWV (RFC 7661) stipulates. I don't think we need to get into defining exactly how to do this, but I'll propose some text that allows senders to do some sort of slow decaying when not pacing.
